XDescription:
X
X        SETPQL is a utility designed for system managers in order to make
X        sure that all users in the SYSUAF file have the minimum recommended
X        process quota limits.  Frequently a new release of VMS or other
X        layered products will require that certain quotas be raised.  The
X        system manager may modify the DEFAULT account, but not each
X        individual user.  Or, the system manager may know that some users
X        already exceed this minimum value, and do not wish to do a global
X        change for all users lest some have their quotas reduced.  SETPQL is
X        designed so that it will only RAISE PQL values, never lower them.
X
X        SYSUAF uses $RMS calls to read the SYSUAF file to obtain each
X        username on the system.  (Unfortunately, there is no "supported"
X        wildcard method of obtaining this list via system service calls).`20
X        $GETUAI and $SETUAI are used to read/modify the process quotas for
X        users who do NOT meet the minimum specified on the command line (or
X        in the DEFAULT account).  The /NOMODIFY qualifier may be used if you
X        wish to only *look* at the account quotas, i.e., to check things
X        before you actually make changes.
X`20
X        The file BUILD.COM may be used to compile and link the modules that
X        form the SETPQL.EXE image.  SETPQL is written in VAX-C and requires
X        a C compiler.`20
X`20
X        The file SETPQL.HLP contains all of the information on the options
X        available with the SETPQL command.  This is the most complete
X        documentation source.
X
XUsage:
X`09$ SETPQL :== "$ dev:`5Bdir`5DSETPQL.EXE"`09! wherever it is located
X`09$ SETPQL `5B/options`5D

X/* General description: Purpose, Usage, Algorithm.
X/*
X/* Purpose:
X/*
X/* To make sure that all accounts in the SYSUAF file meet minimum Process
X/* Quota Limits (specified by the person running the SETPQL program).`20
X/* Frequently, VMS upgrades recommend that the various process quota limits
X/* (ASTLM, MAXDETACH, BYTLM, etc.) for all accounts be raised to some new
X/* value; or the addition of a new software package will require that PQL
X/* values be raised.  Some records in the SYSUAF file may (for whatever
X/* reason) already exceed the minimum recommendatations; therefore, a
X/* wildcard MODIFY within AUTHORIZE may not be wise (it will REDUCE pql
X/* values for those accounts which already exceeded the given value).  This
X/* program is designed to ONLY RAISE, never lower, process quota limits for
X/* specified accounts in SYSUAF.  The default is to check *all* accounts.
X/*
X/* The minimum values for the various process quota limits are taken either
X/* from:
X/* `09- explicit values entered on the command line
X/* `09- values given in SYSUAF for the DEFAULT account
X/* Command line values take precedence over the DEFAULT account values.
X/*
X/* Usage:
X/*
X/* To use the SETPQL.EXE excutable, define a foreign command symbol which
X/* points to the location of the executable image:
X/*
X/* `09`09$ setpql :== "$ device:`5Bdir`5Dsetpql.exe"
X/*
X/* The command is then invoked:
X/*
X/*`09`09$ setpql `5B/qualifiers`5D  `5Buserlist`5D
X/*
X/* where userlist is the list of usernames you wish to check.  Wildcards are
X/* allowed; the default if no userlist is specified is to check all users`20
X/* (i.e., default userlist = "*").
X/*
X/* The legal qualifiers with this command are:
X/*
X/* /`5BNO`5DEXCLUDE
X/*`09/EXCLUDE=( `5BFILE `5B=exclude-file`5D`5D `5B,USER=(userlist)`5D )
X/*`09`09- Do `5BNOT`5D exclude certain accounts from the scan.
X/*`09`09  Default is /EXCLUDE=FILE=SETPQL_EXCLUDE.  The SETPQL_EXCLUDE
X/*`09`09  file will be selected based on:
X/*`09`09`09a) a logical name which points to a file, if this
X/*`09`09`09   exists,`20
X/*`09`09`09b) a SETPQL_EXCLUDE.DAT file in the current default
X/*`09`09`09   directory, if this exists,
X/*`09`09`09c) a SETPQL_EXCLUDE.DAT file in the current user's
X/*`09`09`09   SYS$LOGIN directory, if this exists.
X/*`09`09  If no SETPQL_EXCLUDE file is found, the program will`20
X/*`09`09  issue an information message and continue.
X/*
X/*`09`09  The SETPQL_EXCLUDE file may contain comments (anything
X/*`09`09  following the "!" character).  It should contain a list
X/*`09`09  of USERNAMEs which should be excluded from the scan.
X/*`09`09  The list may contain wildcards.  You may include more
X/*`09`09  than one username per line, delimited by spaces or
X/*`09`09  commas.  NOTE that these must be userNAMEs, not
X/*`09`09  UIC specifications.
X/*
X/*`09`09  You may also explicitly exclude usernames with the
X/*`09`09  form /EXCLUDE=USER=(userlist).  This list may contain
X/*`09`09  wildcards.  Users may be specified by name or by UIC
X/*`09`09  specification.
X/*
X/*`09`09  You may combine these two, as in:
X/*`09`09    $ SETPQL/EXCLUDE=( FILE,  -
X/*`09`09`09`09 `09USER=( *$SERVER, `5BSYS*,*`5D ) )
X/*
X/*
X/* /`5BNO`5DLOG`09- Do `5BNOT`5D log to the SYS$OUTPUT device any informatio
Vn
X/* `09`09  regarding the status of accounts (e.g., which accounts
X/* `09`09  would be modified and how).
X/* `09`09  Default is /LOG.
X/*
X/* /`5BNO`5DMODIFY`09- Do `5BNOT`5D modify the SYSUAF file, merely tell us w
Vhat
X/* `09`09  *WOULD* have been changed.
X/* `09`09  Default is /MODIFY.
X/*
X/* /`5BNO`5DALL`09- Examine all of the PQL parameters.  /NOALL is the defaul
Vt;
X/* `09`09  it implies that only those parameters specifically listed
X/* `09`09  on the command line should be examined.
X/*
X/* Additionally, each PQL in the SYSUAF file has it's own qualifier.  One
X/* example will suffice:
X/*
X/* /`5BNO`5DASTLM`5B=astvalue`5D
X/* `09`09- The /NOASTLM qualifier would specifically request that
X/* `09`09  the ASTLM field be excluded from examination, i.e.,`20
X/* `09`09  ASTLM would be ignored completely.
X/* `09`09  The /ASTLM qualifier by itself would request that`20
X/* `09`09  the specified users' ASTLM be raised (if necessary) to the value
X/* `09`09  of ASTLM for the DEFAULT account.
X/* `09`09  If an astvalue is specified, as in /ASTLM=500, then
X/* `09`09  the value of 500 will be used for all accounts,
X/* `09`09  overriding the DEFAULT account ASTLM.
X/*
X/* The following qualifiers operate in the same manner:
X/* /BIOLM, /BYTLM, /CPUTIME, /DIOLM, /ENQLM, /FILLM, /JTQUOTA, /MAXACCTJOBS,
X/* /MAXDETACH, /MAXJOBS, /PBYTLM, /PGFLQUOTA, /PRCLM, /PRIO, /QUEPRIO,`20
X/* /SHRFILLM, /TQELM, /WSDEFAULT, /WSEXTENT, /WSQUOTA
X/*
X/* NOTE that /CPUTIME is specified as a DELTA-TIME, that is, in the standard
X/* VMS format of "dddd-hh:mm:ss.cc".
X/*
X/* NOTE also that in some cases, a value of 0 implies that the PQL is actual
Vly
X/* infinite.  These are considered; that is, 0 is taken to be a higher value
X/* than any other positive value for these quotas.
X/*
X/* Algorithm:
X/*  `20
X/* A structure to hold all of the various PQL values is declared.  Because
X/* of the different data types of PQL values, the variables within this stru
Vcture
X/* are of different data types (short, long, char, etc.).  For this reason,
V the
X/* values cannot merely be placed in an array.
X/*  `20
X/* An array of addresses which point to the PQL values is declared.  This is
X/* actually a union of different pointer types (short *, long *, char *).`20
X/* these addresses point to the actual PQL values.
X/*
X/* An auxiliary array structure, Info, is declared.  This contains
X/* information on: the textual description of each parameter, whether or not
X/* it was specified on the command line and should be examined, the value
X/* specified on the command line, the data type of each particular process
X/* quota value.  It also holds any flags for special processing of certain
X/* parameters (e.g., cputime or uic).
X/*
X/* The command line is parsed.  The $GETUAI system service is used to
X/* determine the pql values for the DEFAULT account.  These values are
X/* compared with the values entered on the command line; the higher of the
X/* two values is used.  The MasterValue structure is populated with the PQL
X/* values which are to be used.  NOTE that only those PQL values which were
X/* specified on the command line are examined; the others are ignored.
X/*
X/* The SYSUAF file is opened for indexed read access.  A DO-LOOP is entered:
X/* Read the next SYSUAF file to get the next username.  Call $GETUAI to
X/* determine all of this user's PQL values.  For those that we were instruct
Ved
X/* to examine, compare with the MasterValues and select the highest value.
X/* (For those that were not specified on the command line, do nothing, leave
